Sheryl Sandberg, former COO of Meta Platforms, Inc., is leaving the company's board of directors to become an informal adviser in May. Sandberg, who joined Facebook when it was a startup, contributed significantly to its growth. She left her executive role in September 2022 but remained on the board. Sandberg plans to focus on philanthropy, particularly women's leadership and addressing sexual violence in conflict. Meta's revenue soared under her tenure, and despite a recent ad slowdown, the company has rebounded with AI investments. Sandberg's influence extended to workplace reforms in Silicon Valley.
